Density fell below
high limit value;
slug flow test starts
with flow data
retained.
Alarm canceled
as density
exceeded low
limit value.
Density fell below low limit value; as
slug flow test duration expires, a slug
flow alarm is issued with flowrate
clamped at 0.
Density exceeded high limit value; as
slug flow test duration expires, a slug

(2) An example of settings and behavior
・Lower limit density value of slug flow: 0.5 [g/mL]
・Upper limit density value of slug flow: 2.0 [g/mL]
・Slug flow identification time: 10 [sec]
